A500 gel VRLA batteries 12 V, 25–200 Ah
Country: France · Model: A500
The A500 series consists of 12 V gel blocks of 25–200 Ah at the 20-hour discharge rate (C20). It is installed in UPS units, security and fire alarms and telecom equipment, where the battery regularly goes through charge and discharge cycles.

Description
The electrolyte is thickened into a gel using dryfit technology, and the VRLA valve-regulated design keeps the gases inside the block, so water topping up is not provided. Good cycle tolerance is useful at sites where the supply fails often. The capacity is stated at C20, that is, at a 20-hour discharge, so at a short discharge the block delivers noticeably less than the nominal value, which matters when comparing with blocks whose capacity is given at C10. The service life under the EUROBAT 2015 classification is 10–12 years. The blocks comply with IEC 60896-21/22 and have UL, VdS and DNV GL approvals, and VdS interests mainly designers of fire safety systems. The smallest block in the range is the A512/25 G5, the largest is the A512/200 A, and all of them are 12 V.
How to choose
UPS autonomy of an hour or less is calculated from the discharge tables of the specific block, because the C20 nominal value is not reached at such a rate. When a 6 V block or a design life of 15 years is needed, look at the A400 series with a capacity of 20–180 Ah at C10, which also has the FT version with front terminals. For solar plants with frequent deep cycles, SOLAR blocks of 27–230 Ah at C100 or A600 SOLAR 2 V cells with a life of 2400 cycles at 60 % DoD are better suited.

FAQ
Why is the A500 capacity stated at C20 and not at C10?
C20 means the capacity at a 20-hour discharge. At a shorter discharge the block delivers less, so UPS autonomy is calculated from the discharge tables.
What is the service life of A500 batteries?
Under the EUROBAT 2015 classification the series has a service life of 10–12 years. The real life is shortened in a warm room and with incorrect charging.
Are the A500 suitable for fire alarms?
Yes, safety systems are among the main applications of the series. The blocks have VdS, UL and DNV GL approvals and comply with IEC 60896-21/22.
What is the capacity of the smallest and largest A500 block?
The smallest, A512/25 G5, has 25 Ah, the largest, A512/200 A, has 200 Ah, all at 12 V.
Can the A500 be used in cycling duty?
The series withstands regular discharges, but for daily deep cycles in solar plants SOLAR blocks with a life of 800 cycles at 60 % DoD are a better match.
